Chevy Suburban Stabilitrak Issues

Hello, I own a 07 Suburban 1500 LT 4x4. I was driving and the stabilitrak activated my abs brakes and reduced the power to the motor making the vehicle un-driveable. I limped into a big box auto store and they read the code for me before the tow truck arrived ** Code C0455 ** Steering Wheel Position Sensor. I just replaced this and the truck still does the same thing.
I then went through the DIC center and noticed that the tires were not registering any pressures. So I then proceeded to reprogram the tire position in the computer. This failed I tried 3x's to now have a failure in that system ** service tire monitoring system ** I figure this is because of to many failed attempts.
I read the OBDII codes and there are now in the computer.
It did read an B0110 but I think that was in the history of CEL's not entirely sure.
I also inspected the front speed sensors and the connectors are clean with no corrosion.
Brake fluid level is also fine, motor idles fine as well the reduced power is a safety feature not a symptom
Any I mean any helpful input would be great !!!!!
thanks
-Scott

    Hi Scott,
    I checked my resources to see if I could come up with anything helpful for you as you troubleshoot this but as I am limited in technical information was unable to do so. If you decide to work with a dealership, let us know as we're available to assist in that process. Otherwise, I hope that you get some great feedback from the community and are able to get this resolved!

  • Hi Sarah,

    The vehicle was towed to the nearest dealership this afternoon as I was unable to diagnosis any further with out the equipment to read body chassis codes.

    I hope so as well. I have seen that you also represent on the Chevorletforum.com and I have also posted my issue there with a ton of pictures. Same user name.

    It is very frustrating to have read literally hundreds of similar posts with limited to varying results to resolve what seems to be a design issue across many GM platforms: Tahoe, Silverado, Suburban Envoy, Trailblazer. GMC sister models in addition to Cadillac sister model even Corvette was not immune which screams recall or at least a better TSB to resolve this issue.

    I will definitely post the results of what the dealer reports back to me. The failed part, why it failed if they can identify that, the fix required and the over-all customer experience. I have been treated fairly by this dealer in the past. I just need to step back as currently my emotions have the best of me. I may have the wife talk with them until I am able to. I am not accustomed to requiring service on my vehicles as you may have noticed from my posts. I am not a mechanic but I have a very strong background in automotive repair.

    Thanks for letting me vent Sarah and Edmunds I will keep everyone posted with a possible resolution to this issue.

    I have a 2011 Suburban LT with over 120,000 miles. Because of my line of work, I spent quite a bit of time over the road. It started to snow last night and as I was heading home, the engine light was on and the compression to the engine seem to have disappeared while traveling 60 miles per hour. At first it was apparent that some vibration was taking place in the engine And the transmission seems to not have any power transferred while driving in drive gear. It was snowing and I didn't want to be stranded, So I drifted to nearest ramp And shifted the transmission to manual and was able to limp to nearest hotel and put the vehicle in reverse in order to park facing outward. Once I shifted to park the engine sounded like it was sputtering and about to shut down. I had to stay in the hotel overnight. Since this is a first for me, I want to know if the symptoms that I began to see in the vehicle could indicate what went wrong. Since the car is only 1 year old, I did not think that I would have problems with the battery charging but several times in the past few weeks I have seen the battery die and have to be charged. I recently bought a battery to back up this original battery, but have not installed as yet. The check engine light has been intermittent sometimes not coming on at all.. the message Control Panel indicates for the very first time, that there is a stability link traction control problem. I am glad for my sake that there was not a family in the vehicle with me due to the nature of my business, I can't have this occurrence again. Any assistance from the customer service side would be very helpful as we would like this resolved promptly if there is data that suggests that there is frequent product failure in this regard. Limping to a hotel in a snow storm for a problem that is well known to repeat itself with the data that you have collected so far, is of concern.

  • Same exact thing happened to us yesterday on the highway at 120 km per hr with our 2011 LTZ Suburban (120 000 km - highway mileage for work mostly). Side of the roads quite icy and not a great place to be with a young 3 year old aboard. Exit was close by, so made it barely, as the engine power was reduced and could barely go up to 40km per hr on the highway!! Stabilitrak and control traction system lights on as well as Engine light. Engine also sputtering as we parked. Will see the dealership tomorrow for a 3 rd time in 10 days...! (Sensor for gas pump at first - engine light on & engine sputtering, then Service suspension system light on with the air compressor not working as the wires under the gas tank were completely rotten. The cover over them had been cut off by a piece of metal rubbing on it - I guess was not assemble properly, and all the crap got in there ! And now this !!
  • I have a 2007 Suburan that we bought brand new. Have had to put in a new battery twice since purchased. Never really thought anything of it until. On Monday, same thing happened to me as many of the people posting. As I was exiting the fwy, lights came on that said I had no traction, the car sort of shook in the back and then the stability/traction light came on and then it said my car was reducing engine power. Luckily I was exiting the fwy. Pulled over, shut it off and waited about 15 minutes. I originally took the car to my personal mechanic who said the codes were leading to my wiring harness. He did not want to even touch the car and said I should take it to the dealer as this should be a recall issue. Dealer says they want to replace my exceleration pedal, my harness and get my fuel system cleaned up and throttle body cleaned up at the cost of $820. I dont mind paying for my car to be fixed, but from everything ive read, it is not solving the problem of the lights coming on and the car shutting down. I have asked a lot of questions and have come to believe this is an explosion of the electrical system. I am not a mechanic, but it seems as though Chevy has put a lot of bells and whistles on an electrical harness that is not big enough to handle the load. So when anything goes wrong with the car, the electrical system seems to be going haywire setting off the series of lights, and shutting the car down. We also put in an after market alarm that was professionally installed (tried to get one from the dealer, but they said they didn't have them). The dealer is saying that they need to disable my alarm in order for my lock light to shut off. That is going to cost me an additional $100. Sounds like they are just playing a guessing game because they really dont know what to do. Does anyone out there know how to research the wiring on the 2007's as opposed to the year before? I do not, but it seems like this should be addressed before we continue to pay thousands of dollars fixing our cars and have the same problems recur or have a bad accident. I have three young boys and we bought this car thinking it was the safest for them. What a joke!

    I had this problem recently: can went out of stabilitrak without prompting from me. after reading hundreds of forum messages, I thought checking my electrical system might give me a hint. after I opened the hood, I noticed my fuse box cover was not secured properly. considering it is directly above the front left wheel well, It seemed to make sense that it might affect electrical problems.

    it been 2 weeks now, including a significant amount of additional rain, and its been running great with no stabilitrak or electrical issues.

    Summary: check how we'll the fuse box cover is situated. it's not a good design to get on and off correctly. make sure all 4 clips are secure and good luck.

    I have 2007 suburban.....lots of issues since we bought this. Oil consumption problem, many others and now traction/stability issues twice now! What steps can I do to get some where on this. I can't keep going into the shop and forking out money when nothing seems to be clearing up the problem. I understand I will have problems since we are getting up there in miles but this is absurd!
  • Keeciat, It sounds like you have my truck. Honestly I don't say this lightly but factually, sell it. GM did nothing on the oil usage. It is a ring problem that they know failed and they won't fix it properly. The stabilitrac is also a known issue with no resolution from GM.

    My truck was a money pit with all these issues and more service than a 07 should ever see.

    Oil usage test was a complete waste of my time and money!!!!!
    I believe the oil usage was addressed in the 09 model and newer. I'm not sure about the stabilitrac issue though.

    I can go on and on but the best decision I made was to trade it in. Sorry for the negativity but being all the issues I had, dealer & GM non-addressing of these issues and the anger I felt for fixing many issues on my own.

    Again sell it, as you will see from hundreds of posts here & on many other forums there is no answer just tons of complaints, that speaks volumes as to the issues are not being addressed by GM nor are they being taken seriously
